On one of the sides I did - there were the traces of what we could only assume to be some type of explosion (probably a stray explosive from WW2 ..?).
There are also the eagles that were halfway up the spire. Curiously enough, there were six, each one had a number stamped on its head - if you traced the numbers, it made a star composed of 2 equilateral triangles.
It seems the North Tower has since caught fire as well - so the bells will have gone, and all of the stored relics too - so some photos of those.
